# Divide whole numbers with decimal quotients: 5÷2

This video teaches how to divide whole numbers to get a decimal quotient. It explains two methods to achieve this, emphasizing that division can result in decimals, not just whole numbers or remainders. Created by Sal Khan.

• why is doing this hard
• I dont know.All I know is i'm on your side.It's hard.
• Why does it make sense to equate 5/2 as 50 tenths / 2 = 25 tenths = 2.5

But, 12 / .5 = 120 tenths / 5 tenths = 24 and not 24 tenths, which would be 2.4.

How do you decide which equations to drop the extra tenths.

Following the rule of converting to tenths, wouldn't it make sense to say:

50 tenths / 20 tenths =
• Tbh I don't know either...
• do you like these things⌚️📱💻⌨️🖥️🖱️🎮🍣.
• So 5 ÷ 2 = 5/2 ( ) , which as a improper fraction is 2 1/2 ( ). 2 1/2 as a decimal is 2.5 ( ), so 5 ÷ 2 is equal to 2.5, right? Please tell me if I made any mistakes, I'd like to know.

Thx!
• You did not make any mistakes in your calculations, but remember that improper fractions are fractions with a numerator greater than the denominator; 5/2 is already an improper fraction.
Values with both a whole number and a proper fraction combined are mixed numbers, so the 2 (and) 1/2 is a mixed number.
• How am i supposed to do this!
• If you divide 5/2, think about 1/2 of a pizza. If you have 5 of the 1/2 pizzas, you can put two sets of two 1/2 pizzas to make 2 full pizzas, and you still have 1/2 a pizza left, so you have a total of 2 1/2 pizzas. 5/3 would be 1 full pizza and 2/3 left, so 1 2/3.
• How does this make sense like how do you turn a whole number into a fraction then into a decimal! Whats next how to turn 1+1 into a book?
• Actually, turing 1+1 into a book would be easy. But, getting to the point, we can turn a whole number into a fraction by taking something away from it, and then put the number on the bottom on the right side of the decimal, and then putting the top number on the left. For example,
9
9-73/9=1/9
1/9=1.9

I hope this helped! Thx!
• Tbh the video doesn’t really help me with the questions I’m getting, I can easily do five divided by two, but questions I’m getting are seven divided by twenty, which this video doesn’t help answer.
• 7/20 is easy you multiply both numbers by 5 you get 70/100 then put it into a decimal 70/100 = .70
• So 5 ÷ 2 = 5/2 ( ) , which as a improper fraction is 2 1/2 ( ). 2 1/2 as a decimal is 2.5 ( ), so 5 ÷ 2 is equal to 2.5, right? Please tell me if I made any mistakes, I'd like to know.
